Our wet milling and grinding glass beads contain NO FREE SILICA, and are made from superior quality hardened soda lime glass.  These glass beads are processed with state of the art rotating oven technology, developed originally in Europe. This process involves a unique method of rounding, washing, polishing and sieving, and results in a high quality solid glass sphere.  The process uses no hydro-fluoric acid, and thus our glass beads are not only environmentally friendly, they are shiny and uncontaminated.

  • Our Minimum Order For Medium Glass Beads is 2 bags per order.  These beads come in 44 lb containers.
  • Packaging:  44 lb bags on a pallet, 50/pallet = one metric ton (2,200 lbs) per pallet is standard packaging.
  • Glass Bead Applications:
    • Wet Bead Milling
    • Wet Grinding and dispersing media in vertical and horizontal perarl mills for the wet grinding of paints, pigments, dyestuff, ink, argo-chemicals, and minerals.
    • Dispersion of paints, coatings, chemicals
    • Decorative:  Used in wall finishes, plasters, and paints for texture and shimmer
    • Water Filtration: The beads are being used in place of gravel because of their endurance, roundness, and higher crush strength.
